Bernie Sanders and Zohran Mamdani have both said that billionaires should not exist. This information from Grok tells us which countries meet that criteria, and which ones do not.

I asked Grok:

Please list the per capita number of billionaires in each the following countries: the United States, Sweden, Finland, Norway, Denmark, Iceland, France, Germany, Belgium, the Netherlands, the United Kingdom, Canada, Japan, Singapore, South Korea, North Korea, Cuba, Venezuela, Zimbabwe, Eritrea, and Laos. Please rank the list starting with the higher per capita number of billionaires. For each country, list the name of the country, and the number of billionaires per capita. No long essay.

This is the answer that it gave:

Countries with 0 billionaires (North Korea, Cuba, Venezuela, Zimbabwe, Eritrea, Laos) have no recorded billionaires due to economic or political constraints.
